The SRP companies have improved the operation of the whole system including pump-off controllers, better gas separation, gas and solids handling pumps and optimization using surface and bottom-hole cards. Because its wide operation range and adaptability of the system to others wells with minimum cost becomes a economically attractive solution for oilfield development.
